Good Advice from Great Hammerhead. You have to "dip your toe in" at some point. It can become an upgrade process, but that is OK -- I have continuosly sold kits I have outgrown on various forums and sites-- you learn as you go, and you also have to do your homework -- check for new models as well. You can also visit/call one of the reputable UW dealers in your area for help. Someone once told me "it's not the equipment, it's the shooter" -- in otherwords, a great photographer can make great photos with a simple kit -- go forth, be bold and have fun -- that's really what it's about!
